Question
Why does water boil at lower temperatures on
hills?Solution
On higher altitudes such as hills, the atmospheric pressure is lower compared to sea level. This reduced pressure decreases the boiling point of water, causing it to boil at temperatures lower than 100°C, unlike at sea level where it boils at exactly 100°C.
